PERMA - A model of Wellbeing
In this video Martin Seligman explains his theory of PERMA. This theory encompasses the elements of Positive Emotions, Engagement, Positive Relationships, Meaning and Accomplishment. This theory has since been expanded into PERMA+ in which the + incorporates physical activity, nutrition, sleep and optimism.
